Abstract
The utility model provides a self-control type heating device of a railway heat-preserving tank car, and relates to a railway tank car with a heat-preserving structure. The self-control type heating device comprises a steam heating sleeve and a steam heating control system, wherein the steam heating sleeve is arranged on the outer surface of a tank body of the railway heat-preserving tank car and comprises a steam heating cover and a steam distribution groove of a groove-type structure with upper holes and lower holes, the steam distribution groove is distributed in the longitudinal direction along the tank body, is welded to the inner wall of the steam heating cover and is not in contact with the tank body, and the steam heating control system is provided with a steam pipe leading to the steam distribution groove. The self-control type heating device has the advantages that the inner wall of the heating sleeve is provided with the steam distribution groove, so that fast distribution of steam in the heating sleeve is facilitated, the partial temperature is prevented from being too high, uniform heating is facilitated, heating efficiency is improved, unloading can be finished without the need of heating or through slight heating according to weather conditions, unloading time is saved, and the railway transportation problem of normal-temperature fine chemical raw materials easy to solidify in the prior art is solved.
Description
Technical field
A kind of autocontrol heating apparatus of railway insulation tanker, relate to a kind of tank car with insulation construction.
Background technology
Certain organic chemical industry and fine chemical material, temperature is curdled appearance during lower than 20 ℃, by heating, can again become liquid state, during heating for making the unaffected control heating-up temperature that needs of its characteristic.This chemical has strict requirement to accumulating, and the transportation of this chemical at present mainly adopts with the tank container of heat insulation and heating equipment or barreled transportation, and conveying efficiency is low, utilizes the tank car transportation can greatly improve conveying efficiency, saves traffic cost.The domestic existing tank car with insulation and heating function is mainly asphalt truck, and asphalt truck adopts built-in fire tube heating and the insulation of external glass wool, and its type of heating and heat-insulating property can not meet the shipment requirement of this chemical; And the asphalt truck tank shell is carbon steel, easy-to-rust easily pollutes goods carried, also is not suitable for loading and transporting fine chemical material.At present, this kind of chemical utilizes the tank car transportation still to belong to blank at home.
Summary of the invention
Problem to be solved in the utility model is exactly for above deficiency, to provide a kind of heating arrangement to be suitable for loading and transporting normal temperature easily to consolidate the tank car of class fine chemical material.Its technical scheme is as follows:
It comprises steam steam jacket and steam heating control system, the steam steam jacket is located at railway insulation tanker tank body outside face, comprise steam heating cover and distribution of steam groove, the distribution of steam groove is the upper and lower open-celled structure of grooved, along the vertical elongated layout of tank body, be welded in steam heating cover inwall, directly do not contact tank body, the steam heating control system has steam pipe to lead to the distribution of steam groove.
Compared with prior art, the utlity model has following beneficial effect:
1, be provided with the distribution of steam groove at the steam jacket inwall, be convenient to the quick distribution of steam in steam jacket, avoid local temperature too high, be conducive to realize homogeneous heating, improve the efficiency of heating surface, according to weather condition, do not need heating or heat to complete slightly and unload, save the car unloading operation time.Solve the normal temperature described in background technology and easily consolidated the railway transportation problem of class fine chemical material.
2, adopt the steam heating control system to control the steam entered in the steam heating cover, can control the heating-up temperature of steam to material, avoid because excess Temperature causes material rotten.
3, adopt the external large tracts of land shell type type of heating of heating, the efficiency of heating surface is high, is convenient to manufacture, maintenance and the cleaning of tank body simultaneously.
The accompanying drawing explanation
Figure l is that the utility model is for railway insulation tanker structural representation;
Fig. 2 is the utility model steam steam jacket structural representation;
Fig. 3 is Fig. 2 cross-sectional structure schematic diagram;
Fig. 4 is the utility model steam heating control system structural representation;
Fig. 5 is the structural representation of the utility model distribution of steam groove.
The specific embodiment
Referring to Fig. 1～Fig. 5, the utility model comprises steam steam jacket 3 and steam heating control system 2, steam steam jacket 3 is located at railway insulation tanker tank body 1 outside face, comprise steam heating cover 5 and distribution of steam groove 4, distribution of steam groove 4 is the upper and lower open-celled structure of grooved (as shown in Figure 5), along the vertical elongated layout of tank body 1, is welded in steam heating cover 5 inwalls, directly do not contact tank body, steam heating control system 2 has steam pipe to lead to distribution of steam groove 4.
Described steam steam jacket 3 area of heating reaches 70%～80% of tank body 1 external surface area.
Described steam heating control system 2 comprises steam pipe, shutoff valve 6, filter 7 and self-applying temperature control valve 8 are installed on steam pipe, self-applying temperature control valve 8 comprises temperature probe 9 and control cock 10, and control cock 10 connects temperature probe 9 by pipeline, and temperature probe 9 stretches into conveying medium inside.The temperature conditions that temperature probe 9 detects it passes to control cock 10, control cock 10 is according to the size of the temperature signal steam regulation amount of receiving, thereby control by the quantity of steam of steam pipe, so that control the heating-up temperature of steam to material, avoid because excess Temperature causes material rotten.
